Apple vinegar is a kind of beverage, which tastes acidic and alkaline after metabolism in human body. It has the function of neutralizing acidic foods such as fish, meat, eggs, rice and noodles, and is beneficial to the preservation of various nutrients and the absorption of calcium. Most acidic foods contain metal elements such as calcium, potassium, magnesium, iron, sodium, manganese and zinc, such as apples and tomatoes. Although it is sour in the mouth, these organic acids are decomposed into carbon dioxide and various acidic salts in the body and become alkaline. People with alkaline constitution are more immune to viruses than people with acidic constitution.

Of all the apple cider vinegars I know, they are generally a little choking, and occasionally they are ok. Guangdong's "Tianxia No.1" brand apple vinegar is the best in China and can be used as a food aid when friends and relatives get together. It tastes better when it is chilled in summer.

Adults can drink 500ml a day.

Of course, friends with hyperacidity suggest drinking less.
